NORMAN — The University of Oklahoma Athletics Department announced Wednesday that it has reached an agreement with the University of Nebraska to play an additional two games in the schools' upcoming football series.

The Sooners and Cornhuskers, who were already scheduled to renew their rivalry in Norman on Sept. 18, 2021, and play in Lincoln on Sept. 17, 2022, will now also meet in the 2029 and 2030 seasons, it was revealed by OU athletics director Joe Castiglione and Nebraska athletics director Shawn Eichorst. The 2029 contest will take place Sept. 15 in Norman and the 2030 contest will be played Sept. 14 in Lincoln.

Longtime intraconference rivals, OU holds a 45-38-3 all-time lead against Nebraska in a series that was played annually from 1928 to 1997. The programs haven't met since the 2010 Big 12 Championship Game, a 23-20 Sooners win on Dec. 4 in Arlington, Texas.

"Oklahoma and Nebraska are two of the most iconic programs in college football history," said Castiglione, "and we were excited a few years ago when we were able to rekindle the storied series by scheduling games for 2021 and 2022. We feel the same way with the addition of the games in 2029 and 2030. Fans of both programs are extremely passionate and loyal, and we're happy we can preserve — and extend — the on-field history of two of the game's all-time greats."

The most storied game in this historic series is the fabled 1971 "Game of the Century" in Norman that featured No. 2 Oklahoma and No. 1 Nebraska as the Cornhuskers prevailed by a 35-31 count. The game in 2021 will commemorate the 50th anniversary of that classic OU-Nebraska contest.

The two teams also entered their 1987 contest ranked atop the AP poll, as Barry Switzer's No. 2 Sooners captured a 17-7 win over Tom Osborne's No. 1 Cornhuskers in Lincoln. In 2000, an OU team ranked No. 2 in the BCS standings under head coach Bob Stoops posted a 31-14 home win over No. 1 Nebraska (coached by Frank Solich) and eventually won the national title with a 13-0 record.

Oklahoma has won six of its eight last meetings with Nebraska under Stoops. The Sooners also prevailed by a 21-7 margin in the 2006 Big 12 Championship Game played at Arrowhead Stadium in Kansas City.

During Stoops' tenure with the Sooners, Oklahoma has faced some of the top programs in college football during the regular season. That list includes Notre Dame (1999, 2012, 2013), Alabama (2002, 2003), Oregon (2004, 2006), UCLA (2005), Washington (2006, 2008), Miami (2007), Florida State (2010, 2011) and Tennessee (2014, 2015).
